be put upon the stretch. The fourth and following joints 
are a third shorter than the foregoing and are nearly equal 
and square in their outline, each successive joint very 
slightly increasing in thickness and diminishing in length. 
The last joint is about thrice as long as the one preceding 
it, of an oval or subovate form, rounded at its base and 
bluntly jointed at its apex, and is probably composed as 
in the other species of this genus of three joints compactly 
united together., The thorax scarcely equals the head in 
width and is egg-shaped and thrice as long as wide. On 
each shoulder is a slightly impressed line extending 
obliquely backward and inward. The abdomen is a third 
shorter than the thorax, and in the livte insect surpasses 
it in thickness, is egg-shaped and convex with its tips acute- 
pointed. When dried it scarcely equals the thorax in 
thickness and becomes strongly concaVe on the back and 
triangular when viewed on one side. It is smooth, polished 
and sparkling, of a green black color, the middle segments 
each with a broad purple black band visible in particular 
reflections of the light. Beneath it is black and at the tip 
shows some fine impressed longitudinal lines forming the 
edges of the grooVe in which the sting is enclosed. The 
legs are slender, pale wax yellow, with the feet and ends of 
the shanks dull white, the hips of the hind legs being 
stout and black, with their outer faces green blue and their 
tips pale yellow. The feet are fiVe-jointed and dusky at 
their tips. The wings are transparent and reach slightly 
beyond the tip of the abdomen when at rest. Th'e anterior 
ones are broad and evenly rounded at their ends, and have, 
near the outer margin, a thick brown rib or subcostal vtein, 
extending more than a third of their lengths and then 
uniting with the margin and terminating some distance 
forward of the tip, after sending off a short straight 
stigmal branch which is thickened at its end, with apex 
notched. Towards the inner margin an exceedingly fine 
longitudinal vein* is perceptible, which, near its middle 
gives off a fine branch running almost to the inner hind 
end of the wing. The hind wings are much smaller and 
without veins, except a brown subcostal onfe which extends 
into the outer margin and abruptly ends a little beyond 
the middle.
